All I Need is the Air That I Breathed: Microbial Dairies Using CO2, Sunlight and Water

Submitted by on December 5, 2014 – 2:36 pmNo Comment

by Jim Lane (Biofuels Digest)  Take CO2, add water and an energy source: voila, Fuels & Chemicals from Microbial Dairies.  We revisit 3 top practitioners of the art and one outlier, and their progress.

There are a number of technologies based on the dairy model, or “milking mode”, where the organisms are optimized to secrete targeted products, which are recovered from a broth surrounding them. In this case, a number of technology developers are still of the opinion that fuels-grade economics are possible, though speciality chemicals may also be produced to sweeten the margins. And in this case, the organisms are photoautotropic (meaning they get energy from sunlight, and carbon from CO2).
